SPECIFICATION forming part of Letters Patent No. 418,732, dated January'7, 1890.

Application mea .my ze, 18,89. l

To @ZZ whom t may concern:

Be it known that I, AMOs LYNCH, a citizen of the United States,residing` at Eugene City, in the county of Lane and State of Oregon,have invented certain new and useful Improvements inRailroad-CarCouplings, of which the following is a specification,reference being had therein to the accompanying dra-wings.

This invention relates to car-couplings; and it consists of an improvedconstruction of draw-heads, draw-bars, and coupling-head andconnections, as described and claimed In the accompanying drawings,Figure lis a side viewofmy improved car-coupling, representing the partscoupled. Fig. 2 is a sectional plan of the coupling-head and a drawbarwith a locking device holding the head in position for coupling. Fig. 3shows the two ends of the coupling-head. Figs. 4 and 5 are plan views ofa double draw-head, showing dierent ,adj ustments of the same.

A designates a draw-head, in which is secured a draw-bar d by means of apin c, the saiddraw-bar being provided at its coupling end with flangesor Wings e, for connection with a rotary coupling-head B, which isplaced between the draw-heads. The said rotary head is cylindrical and'Ahollow, and has an opening a at one end, which conforms to the couplingend of the draw-bar a, so asto` admitsaid bar when the head B is inposition for coupling, and to retain said bar after it has entered thehead and the latter has been turned, as hereinafter set forth. Theopposite end of the head B has a circular aperture for a draw-bar b,which is connected with the draw-head C by a pin d, the said draw-barextending into a tubular recess in said draw-head. Two recesses g aremade in the end of the head B, which is toward the draw-head O, one ofsaid recesses being on each side of the aperture through which thedraw-bar b passes, (see `Fig. 3,) said recesses being intended toreceive a catch or detent which connects with the rotary head, ashereinafter stated. The vhead B has the opposite slots f, and isprovided with a weighted arm D, which extends laterally from the head,so that, the latter, when re-V- leased from the detent, is turned bygravserii Notsiees. (nommen 4 ity, the coupling being thus automaticallyeffected. The bolt b has an enlargement, by flanges orotherwise, on itsend which is in the rotary head, thus forming a swivel-connectionbetween the rotary head andthe draw-head C. The said draw-bar b is madef hollow, and a p in or small bolt 7L is inserted therein. On a reducedpart of the bolt h is placed a spring c', which tends to Ypress saidbolt forward in position for contact with the draw-bar a when the latterenters the head B. Rigidly attached to the bolt h is a rectangular catchor detent m, which extends through a slot n in the hollow bar b, and isin position to connect with the head B in either of the recesses g,according to the position in which the head, with its weighted arm D, isset for the purpose of coupling, and

lock the head in position to receive the drawbar a. The arm D has twochains or cords lo attached to it, to be severally used by a person oneither side of a train to raise said arm to a horizontal position andturn the head B to its position for coupling or for uncoupling. When theparts are coupled,the arm D is pendent from the head B, and the catch mbears against the end of the head; but when the said arm is raised to ahorizontal position on either side the said catch enters a recess g inthe Ahead and the latter is thus locked in position to receive thedrawbar a.

The cars being moved together, the drawbar a enters the head B andpushes back the bolt h, thus releasing the head B from the catch m, andthe head being turned by gravity one-quarter of a revolution, thecoupling end of bar a is secured in the head and the coupling is thuseffected. When it is desired to uncouple, an attendant at either sidecan,

by means of a cord k, raise the arm D to a horizontal position, when thehead will be locked by the catch m, and the bar a may be withdrawn.

The double draw-head C is constructed in two parts which are coupledtogether by a bolt o, the stock or main part being intended to befastened to a car. The forward part of the draw-head C may be turnedv onthe pivotal bolt o, and is provided with two mouths E and E', arrangedat a right angle with each other, as shown. The mouth E has an openinglike that of the draw-head A, and receives and usually carries adraw-bar a. The mouth E is constructed to receive a drawbar b, and isrecessed at s to admit the catch m, so that the head B may be broughtclosely to it, as seen in Fig. 1. The stock or main part of C isprovided with a base or support p for the forward part, the latter beingturned on its pivot as may be desired.

The double draw-head is adapted to be attached to the tender, and may bereadily shifted for connection with either end of rotary head B, eitherof the mouths E E being used, as occasion may require. Y

A draw-head substantially in the form of the draw-head A, but providedwith a recessed mouth like E', may be used in connection with a draw-barl) for coupling cars.

I claiml. In a car-coupling, the combination,\vith a hollow rotary headwhich is laterally weighted, of a draw-bar constructed to enter saidhead at one end and couple therewith, a hollow draw-bar which is looselyconnected with said head at the opposite end, and a spring-bolt which isinserted in said hollow draw-bar and is provided with a catch which isadapted to connect-with said rotary head, substantially as and for thepurposes set forth.

2. The combination, with a hollow rotary head B, provided with a lateralweight D and one or more recesses g, of a hollow draw-bar b, providedwith a spring-bolt h, which is provided with a catch m, which is inposition to enter a recess g in said rotary head, substantially asdescribed, for the purposes set forth.

3. In combination with the rotary head B, a draw-head C, constructed intwo parts which are pivotally connected, one of said parts beingprovided with two mouths E E which extend at a right angle with eachother, substantially as'described, for the purposes set forth.

In testimony whereof I do aflix mysignature in presence of twowitnesses.

AMOS LYNCH.
